Loon powered emergency networks for flood affected Peru

In the past, when earthquake and floods used to take out mobile connectivity, satellite used to be the only way forward. See here for instance for use of satellite connectivity in Nepal and Japan. I really like the Network in a backpack from Vodafone picture in that post.

Having said that, things have moved on in the last few years. In my earlier post I discussed about Telefonica's network in a box that weighs just 40 grams. This can be deployed in conjunction with a drone or a Helikite and you have a self-contained coverage. EE is taking this further and plans to connect Scotland using Airmasts and Droneways.

In the recent floods in Peru, Telefonica worked with Google Loon team to to re-connect the service and re-establish mobile communications, which are particularly crucial in such dire circumstances. According to their blog:

Telefónica and Project Loon brought basic Internet connectivity across more than 40,000 Km2, providing over 160 GB worth of data –enough to send and receive roughly 30 million WhatsApp messages, or 2 million emails.

The Google Loon team have their own blog posts on this topic here and here.

The picture on the top is a modified picture from Project Loon that explains how the Loon's work. Fundamentally the working is sort of the same, regardless of the technology you use. As I explained in my other post here, when you use Helikites for example and create a mesh network its similar to the Loon's using laser for connectivity between them. All technologies need backhaul to connect to the outside world and access to connect to the end user.
